Take a look at this: https://github.com/mongodb/node-mongodb-native/blob/ccc5e3042b0f52d990a517bca224434bdfbd4728/src/sessions.ts#L457

This typescript definition is wrong, even when compared to the method's readme:

`async withTransaction<T = void>(fn: WithTransactionCallback<T>, options?: TransactionOptions
  ): Promise<Document | undefined>`

This is the actual data returned, and as you can see, it is nowhere close to the Document type:

To work around this problem, I had to create a wrapper method which redefines types.

Please help in fixing the type definition. Thanks.
